Guaranteed snapshot space and restoring question
Posted: Thu Aug 22, 2019 4:02 pm
Probably a dumb question but... Am setting up a new set of disks from scratch and want to enable snapshots, with guaranteed snapshot space.
Say I have single storage pool occupying the entire Raid-5 disk space of 30TB, create a single thick volume of 25TB, and set a guaranteed snapshot space of 5TB.
I then fill that thick volume with 23TB of files.
Then later I accidentally delete ALL those 23TB of files.
I know the guaranteed snapshot space represents the maximum size of changes tracked, but assuming I don't create large amounts of new data on the volume then in this case I should still be able to restore ALL those 23TB of files...... is this correct? Or no?
